Abstract: A pneumatically assisted inflator for gas cylinders inflator piston (24) positioned within a piston cylinder (26) that moves against a rotatable cam surface (16S), on a rotatable collar (16C) connected to a pull lanyard (20), to force a pierce pin (32) to make at least a small pin hole in a frangible seal (28) and allow high pressure gas from the gas cylinder to flow into the piston cylinder (26), whereupon the high pressure gas in the piston cylinder (26) further moves the inflator piston (24) to more fully force the pierce pin (32) into the frangible seal (28) to fully open the frangible seal (28).

Abstract: A pneumatically assisted inflator for gas cylinders comprises an inline configuration such that gas contained within the gas cylinder flows axially through the inflator to be exhausted therefrom and inflate an inflatable article. The inline configuration of the inflator reduces the stress otherwise imparted to the component parts thereof and thereby allows most of the component parts to be manufactured from an injection molded high-strength plastic or the like. The inflator comprises an inflator piston positioned within a piston cylinder that moves against a rotatable cam surface, such as a rotatable collar connected to a pull lanyard, to force a pierce pin to make at least a small pin hole in a frangible seal and allow high pressure gas from the gas cylinder to flow into the piston cylinder, whereupon the high pressure gas in the piston cylinder further moves the inflator piston to more fully force the pierce pin into the frangible seal to fully open the frangible seal.

Abstract translation: 用于气瓶的气动辅助充气机包括内联构造，使得容纳在气瓶内的气体轴向流动通过充气机从其中排出并使其膨胀。 充气机的在线构造减少了赋予其组成部分的应力，从而允许大部分组成部件由注射成型的高强度塑料等制造。 充气机包括位于活塞气缸内的充气器活塞，其抵靠可旋转的凸轮表面移动，例如连接到拉索上的可旋转轴环，以迫使穿孔销在易碎密封件中至少形成小的销孔，并允许高 来自气瓶的压力气体流入活塞气缸，于是活塞气缸中的高压气体进一步移动充气活塞，以更充分地迫使穿孔销进入易碎密封件以完全打开易碎密封件。
